Radio frequency-based repeater in a waveguide system

Abstract

A system of a machine includes a network of a plurality of nodes distributed throughout the machine. Each of the nodes is operable to communicate through a plurality of electromagnetic signals. A controller is operable to communicate with the network of nodes through the electromagnetic signals. The system also includes a plurality of waveguides configured to guide transmission of the electromagnetic signals between the controller and one or more of the nodes. A radio frequency-based repeater is coupled to at least two of the waveguides in the network between the controller and at least one of the nodes. The radio frequency-based repeater is configured to receive a portion of the electromagnetic signals in a first waveguide and boost a transmission characteristic of the portion of the electromagnetic signals in a second waveguide.

AI Technical Summary

Benefits of technology

The patent describes a system for improving communication in a machine by using radio frequency-based repeaters. These repeaters are placed throughout the machine and connected to nodes that communicate through electromagnetic signals. The repeaters boost the transmission of the signals in a specific waveguide, improving the overall quality of the communication. The system can be used in gas turbine engines and other machines to enhance the transmission of data and improve the performance of the communication network.

Problems solved by technology

As control and health monitoring systems become more complex, the interconnect count between system components increases, which also increases failure probabilities.

With the increase in interconnects, troubleshooting systems may not always identify the contributing faulty components reliably when system anomalies occur.

Failures associated with such systems are often due to connection system failures, including: sensors, wiring, and connectors that provide interconnection (e.g., signal and power) between all components.

Difficulties can arise when troubleshooting these complex interconnected systems, especially when the systems include subsystems having electronic components connected to control system devices, such as actuators, valves or sensors.

For example, a noisy signal in a sensor reading could be caused by a faulty interface circuit in the electronic component, a faulty wire or short(s) in the cable system, and / or a faulty or intermittent sensor.

The time associated with identifying a faulty component quickly and accurately affects operational reliability.

The access limitations make wire routing bulky, expensive and vulnerable to interconnect failures.

The sensor and interconnect operating environments for desired sensor locations often exceed the capability of the interconnect systems.

In some cases, cable cost, volume and weight exceed the desired limits for practical applications.

Application of electromagnetic sensor and effector technologies to address the wiring constraints faces the challenge of providing reliable communications in a potentially unknown environment with potential interference from internal or external sources.

Large-scale deployments of multiple sensors and / or effectors with varying signal path lengths further increases the challenges of normal operation and fault detection in a network of connected nodes.
